Abstract (en)
[origin: EP0405016A1] Electrophotographic method of obtaining lithographic printing plates comprising the following steps : (i) uniformly electrostatically charging a photoconductor element, (ii) image-wise discharging said photoconductor element, (iii) developing the resulting electrostatic charge pattern with dry toner particles of which more than 90 % by volume have an equivalent particle size diameter less than 10 microns and more than 50 % by volume have an equivalent particle size diameter less than 7 microns, (iv) electrostatically transferring the developed image to a toner receiving plate, said toner receiving plate comprising a plastic film support that is thermostable to a temperature of at least 140 DEG C and a crosslinked hydrophilic layer thereon, said layer containing infrared absorbing substances in such an amount that the reflection density of said layer in the visible spectrum is between 0.4 and 1.4, and (v) fixing the transferred toner to said toner receiving plte by infrared radiation fusing.
